Contraindications of Gastrodia elata

Because Gastrodia elata has a significant effect on headaches, dizziness, etc. caused by hyperactivity of liver yang, it is often taken as a tonic. As soon as dizziness occurs, regardless of whether the constitution is weak or strong, the qi and blood are strong or weak, Gastrodia elata is used indiscriminately, and the result may be the same adverse reactions as the above patients.

Common adverse reactions that occur when taking Gastrodia elata include: dizziness, nausea, chest tightness, skin pimples with itching, etc. In some cases, facial or whole body edema, and even hair loss may occur. Not only will such reactions occur when using Gastrodia elata alone, some people will also develop symptoms of allergies to Gastrodia elata after taking gastrodia elata-containing decoctions such as Banxia Atractylodes and Gastrodia elata decoction, and Chinese patent medicines such as Gastrodia elata pills and Gastrodia Armillaria sugar-coated tablets. .

The ancients have long known about the side effects or taboos of Gastrodia elata. As the "Compendium of Materia Medica" says: "If you take Gastrodia elata for a long time, red elixirs will appear all over your body." "Ben Jing Feng Yuan" also says: "Although Gastrodia Gastrodia is not drying in nature, it is still a wind preparation. It should not be used indiscriminately if there is blood deficiency, no wind, burning headache, dry mouth and constipation." ?

Wu Yiluo, a famous doctor in the Qing Dynasty, even said bluntly: "It should not be used by people with weak blood and non-true strokes." Modern pharmacological experiments have proven that Gastrodia elata has certain toxic and side effects. The toxic dose of Gastrodia elata is more than 40 grams, and the incubation period of poisoning is 1 to 6 hours.

The general dosage of Gastrodia elata for adults can be 10-30 grams, which can be taken by boiling water or stewing chicken and pigeons in batches a day. Precautions for Gastrodia elata

1. Any patient with decreased body fluid, blood deficiency, yin deficiency, etc. should use Gastrodia elata with caution.

2. Pay attention to compatibility and application. "Compendium of Materia Medica" has a description of using Gastrodia elata with other medicines and then seeing its effects. Ancient and modern doctors rarely use Gastrodia elata as a single ingredient, but mostly use prescriptions based on different diseases and syndromes. Such as: Banxia Atractylodes and Tianma Decoction, Gastrodia Uncaria Drink, Gastrodia Pills, etc. It has been clinically proven that Gastrodia elata alone has poor or uncertain effects.

3. Even when treating symptoms such as hyperactivity of liver yang and phlegm blocking the meridians, when using Gastrodia elata, it is necessary to carefully examine the condition, grasp the pathogenesis, and add or subtract according to the symptoms, in order to achieve good therapeutic effects.

4. Gastrodia elata should not be fried together for a long time. The main component of Gastrodia elata is Gastroside, which is highly volatile when exposed to heat. Decoction of Gastrodia elata and other medicines will lose the effective sedative and analgesic ingredients due to heat. Therefore, it is best to moisten Gastrodia elata with a small amount of water first, then cut it into thin slices after softening, dry or dry it in the sun and grind it into powder, then drink it with the decoction, or grind it into pills or powder.
